Embodiment 1

[0040] A variety of waste gas comprehensive treatment systems, such as attached figure 1 As shown, it includes the exhaust gas comprehensive treatment subsystem 1 and the workshop unorganized exhaust gas pretreatment subsystem 2, the inorganic exhaust gas pretreatment subsystem 3 and the organic exhaust gas pretreatment subsystem respectively connected to the total intake pipe 16 of the exhaust gas comprehensive treatment subsystem 1. System 4.

[0041] Here, as attached figure 2 As shown, the exhaust gas comprehensive treatment subsystem 1 mainly includes a water spray absorption tower 11 , a liquid alkali spray absorption tower 12 and an oxidation reaction tower 13 connected in series in sequence. Wherein, the total air intake pipe 16 is connected with the position near the bottom of the water spray absorption tower 11, and the top of the water spray absorption tower 11 is connected with the position near the bottom of the liquid alkali spray absorption tower 12, and the l...

Embodiment 2

[0048] A variety of exhaust gas comprehensive treatment systems, based on the first embodiment, the alkali absorption liquid in the liquid alkali spray absorption tower 12 is a calcium hydroxide saturated solution, so that not only the acid gas can be absorbed, but also due to the cost of calcium hydroxide Inexpensive, thereby reducing costs in the waste gas treatment process. Moreover, calcium ions can also produce precipitation with carbonate, sulfite, and sulfate, and these precipitations can be used as raw materials for the production of gypsum, which greatly improves the economic benefits of the waste gas treatment process.

[0049] In addition, the oxidizing liquid in the oxidation reaction tower 13 here is mainly hydrogen peroxide. On the one hand, the hydrogen peroxide can directly absorb waste gas for oxidation. Oxygen is easily converted into ozone under the irradiation of the ultraviolet lamp 131 , so that the oxidative decomposition of exhaust gas can be further ac...

Embodiment 3

[0051] A variety of waste gas comprehensive treatment systems, based on the second embodiment, as attached Figure 6 As shown, the water absorption tank 31 and the other two alkali absorption tanks 31 of the inorganic waste gas pretreatment subsystem 3 are also connected to the waste water pool through the same waste water pipe 34 .

Abstract

The invention provides a system for comprehensively treating multiple types of exhaust gases and relates to the field of exhaust gas treatment. The system mainly comprises a comprehensive exhaust gastreatment subsystem and a workshop discorded exhaust gas pretreatment subsystem, an inorganic exhaust gas pretreatment subsystem and an organic exhaust gas pretreatment subsystem which are respectively connected with the comprehensive exhaust gas treatment subsystem. The system can simultaneously treat multiple types of exhaust gases, so that the space occupied by equipment is greatly decreased, meanwhile energy waste is also reduced. Accordingly, the economic benefit of exhaust gas treatment is greatly increased.

Description

technical field [0001] The invention relates to the field of waste gas treatment, in particular to various waste gas comprehensive treatment systems. Background technique [0002] Environmental protection is an issue of concern in today's social development, especially recently, the state's supervision of corporate environmental protection has also been continuously strengthened. Therefore, enterprises are more systematically equipped with various equipment or systems to deal with pollution sources. [0003] Among them, chemical production enterprises are the main focus of the country today. They not only produce a large amount of waste water in the production process, but also produce a variety of waste gases, such as unorganized gases in workshop reaction tanks, inorganic water-soluble gases and High concentration of organic gas. When dealing with a variety of waste gases, under normal circumstances, companies often design separate treatment equipment or treatment system...
